General Description
The HMC538LP4(E) are Analog Phase Shift-
ers which are controlled via an analog control
voltage from 0 to +5V. The HMC538LP4(E)pro-
vides a continuously variable phase shift of 0 to
800 degrees at 6 GHz, and 0 to 450 degrees at
16 GHz, with consistent insertion loss versus phase
shift. The phase shift is monotonic with respect to
control voltage. The control port has a modulation
bandwidth of 50 MHz. The low insertion loss and
compact size enable this part to be used in a wide
range of applications, including the phase adjustment
of clocks in fiber optic systems and test equipment.
THe HMC538LP4(E) is housed in leadless QFN sur-
face mount packages and are available in both stan-
dard and RoHS compliant versions.
